He was born on 2nd August 1861 in Khulna,Bangladesh.Born to a rich landowner, he was younger of two brotheres.He was a great scientits known for his contribution towards the chemistry stream.
Despite the illness during his childhood days forced him to discontinue studies for a while but he made the best use of that time too and pursued the Higher education from the 'University of Edinburgh' and done his further research for a year there.
He got famous by his works on nitries and hyponitrites of metals, especially mercury does work for him worldwide
He knew for his work of starting the first ever Chemical Landmark Plaque outside the Europe, for which he got honored by the Royal Society of Chemistry.
2.Srinivasa Ramanujan(1887-1920)
He was born in Erode town in TamilNadu on 22nd December 1887. He was a great scientits and greatest Mathematician. He got fame at the age of twenty-six.
The surprising fact we get to know about his life that even his college education was not completed due to his illness.
He was considered as the master of the theory of numbers. In 1914 the formula for p(n), the number of partition of 'n' was his outstanding contribution.

3.C.V.RAMAN(1888-1970)
He was born on 7th November 1888 near a small village in Tiruchirapalli was the genius of Physics.His father was initially a teacher and later became a lecture in mathematics and physics in one of Vishakhapatnam college.
From the age of 11, he passed the matriculation examination as a brillant student even though at age 13 he also passed his F.A examination with the scholarship . in 1920 in Madras he joined Presidency College and received his B.A physics in 1904.
Gretest invention he did for our nation and make us proud by his discovering the "Raman Effect" or we can say the inelastic scattering of the photon.The experimentation was based on that when light traverses a transparent material,some of the deflected light changes in wavelength
He won 1930 Nobel Prize in physics for the "Raman Effect and become the first Indian to win Nobel Prize in sciences,and in 1957 he was also honored with Bharat Ratna
